SANITARY HOG-THOUGH.

Specification of Letters Patent.

Patented Jan. 14, 1919.

Application filed February 25, 1918. Serial No. 219.160.

To aZZ whom it may concern:

Be it known that 1, JOHN DOBRY, a citizen of the United States, residing at Cedar Rapids, in the county of Linn and State of Iowa, have invented certain new and useful Improvements in Sanitary Hog-Troughs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide a sanitary hog-trough, so constructed as to prevent the feeding animals from getting into it with their feet, and to be easily and quickly cleaned.

The invention is fully disclosed in the description and claims following, reference being had to the accompanying drawing, in which z- Figure l is a view in perspective of my improved hog-trough as in use. Fig. 2 is a plan View of the same, with the guards folded down for convenience in cleaning the trough. Fig. 3 is a section at 3-3 of Fig. 2, showing the construction at the ends. Fig. 4 is a longitudinal section of the same. Fig. 5 is a fragmentary section, showing the con nection of the guard-supporting arms with the side rails of the trough.

, In the drawing, 1 denotes the main body of the trough, preferably formed of gal vanized sheet steel, and at its upper edges reinforced with angle-bar side rails 2. The ends of the trough are preferably malleable castings 3 provided with extended feet 4 to give the trough a stable base. The sides of the trough are suitably secured to side flanges 5 of the end castings, as by, rivets 6, the trough being set inside the flanges. At the bottom, however, it is desirable to have the flange 7 inside the trough, so that the heads of the fastening rivets may finish flush with the surface, the flange being countersunk therefor. This leaves a perfectly smooth surface, with nothing to obstruct the edge of a shovel used in cleaning the the flange is brought to a thin edge, as shown in Fig. 4c. The operator may now shovel the refuse from the bottom of the trough toward the ends thereof, carrying it up when the shovel reaches the end, and with no obstruction to the scraping action of the shovel. Intermediate footings 9 are provided conformlng in outline to the ends, and riveted to the sides at 10. The cross-bars of these footbrackets are necessarily outside (below) the trough, but at this part of the trough the rivet heads 11 are not objectionable, as at the ends. In Fig. 3 it will be seen that the heads of the rivets lie close to the sheet metal body 1. To make a tight joint with but few rivets a stiffening strip 3 may be placed below the sheet metal, as shown by a section of the part in Fig. 4, the rivets passing through all three parts, as indicated.

At intervals in the side rails are formed slots 12, and in these are mounted arms or standards 13, curved at 14 to permit them to turn downwardly in one direction. Shoulders at 15, together with the toe of the hook 14, lock them in one direction, when in vertical position. At the upper end of each is a notch 16. These standards are arranged in gangs each side, and in opposite order as to the sides, so that when in operative position, as shown in Fig.1, the notches of the respective standards interlock, and preferably by forcibly springing them far enough to allow for the interlocking. When so interlocked, they mutually hold the locked position, but to prevent the possibility of disengagement by the crowding of the feeding animals, a pair of them may be latched by a hook 17. Each gang is connected by a bar 18 hinged to them at 19, to which the latch-hook is connected. One end of each connecting bar is extended downwardly and orms a loop 20 to receive a central bar 21, which may be removed at will. The bar serves as a guard when the trough is used for pigs, but is removed when the trough is used for adult hogs.

The trough as thus constructed eliminates much of the filth usually attending the feed ing of hogs, and due to their climbing into it with their feet. It does not, however, remove the necessity for frequent cleaning of the trough of refuse feed, that it may be clean andsanitary. In order that this may be done conveniently the guards should be out of the way of the shoveler, and this is effected in a moment by unlatching the'hook 17, forcibly unlocking the standards by pulling the connecting bars in opposite directions, and letting them down to the collapsed position shown in Fig. 2. There is then nothing in the way, and the trough may be easily and quickly cleaned with a shovel, broom and water.

In forming the flanges ofthe trough-ends narrow gaps are left between the side and bottom flanges for the insertion of the sheet metal, as shown in Fig. 3.

Referring to Fig. 5, it will be seen that on the side of the standard opposite the shoulder 15 is a small projection 22, which serves as a fulcrum or turning point for the standard, and insures free and easy movement of the hook let in the slot 12.

' Having thus described my invention, I claim:

'1. A hog-trough with sides and bottom formed of sheet metal, and ends to which the trough bony is attached, the ends having outer side flanges to connect with the sides of the trough, and inner bottom flanges separated therefrom by narrow gaps to admit the sheet metal, the bottom flanges being thinned to an edge, and countersunk to receive flush rivets.

2. A heg trough with sides. and bottom formed of sheet metal, and ends therefor having laterally extended feet, outer side flanges, and inner, bottom flanges separated therefrom by narrow gaps to admit the sheet metal, said bottom flanges being countersunk to receive flush rivets, and thinned to an ed e substantially as and for the ur ose set forth.

'3. A hogtrough provided with laterally extending top-rails slotted at intervals, standards pivot-ally mounted in said slots, oppositely disposed across the trough, and suitably notched for mutual engagement, and bars connecting each gang of standards pivotally, whereby the bars serve as guards when the standards are interlocked, and the whole may be collapsed when not in position for use.

4. In a hog-trough, the combination with the trough proper, of a foldable guard therefor, comprising a plurality of standards hinged to the sides of the trough, and adapted to interlock when elevated, and guardbars pivotally connecting with the respective gangs of standards.

5. In combination with a hog-trough, foldable guards therefor, comprising a plu rality 01": standards hinged at each side of the trough to turn downwardly in opposite Gopies of thisv patent may be obtained for directions on the respectively opposite sides thereof, the movement of the standards being limited in the other direction to the vertical, except as sprung forcibly, and con necting guard-bars hinged to the standards near their upper ends.

6. The combination of a hog-trough, a toldable guard hinged at each side and adapted to turn down in respectively oppo site directions, means adapted to limit the movement in the other direction to a predetermined elevation, and means adapted to hold the guards in mutually interlocked position.

7. The combination of a hog-trough, a plurality of standards hinged at each side and adapted to mutually interlock when turned to elevated position, guard-bars hinged to each gang of standards, and having terminal loops depending centrally when in elevated position, and a removable bar insertible in said loops.

8.'The combination with a hog-trough having outwardly flanged and slotted side rails, of a plurality of standards having hooked and shouldered ends fitting in said slots, whereby the standards may turn down but one way from the vertical, the gangs on respective sides being oppositely disposed, and the standards being notched near the upper ends for mutual engagement, and connecting guard-bars hinged to the respective gangs of standards.

9. The combination with a hog-trough having outwardly flanged and slotted side rails, of a plurality of standards having hooked and shouldered ends fitting in said slots, and having projections opposite the shoulders to form turning points for the standards, the gangs of standards being op positely disposed on opposite sides of the trough, mutually engageable, and connected by side-bars.

In testimony whereof I afiix my signature in presence of two witnesses.
